Upper intake level
Adults, 40mg a day, from food and supplements together. One serving of this product holds 30mg, less than that level on its own.
An upper intake level is the largest daily intake unlikely to cause harm for most people. It is not a limit on treatment. It does not apply to someone taking zinc as a medical treatment. It is not a recommendation about what to take.

In whole units
1 capsule = 30mg for $0.228
This is the smallest whole number of capsules that holds at least one comparison dose. It is shown as a caveat and is deliberately not used in ranking, because rounding up changes the amount as well as the price.
- One capsule holds 30 mg of elemental zinc, 2 times the 15 mg comparison dose. Capsules cannot be split.
- Elemental zinc as printed on this package's own panel: "Zinc (as Zinc Picolinate) 30 mg 273%". It is not derived from a salt weight, which the panel does not print. The panel carries no "Servings Per Container" line; the serving is one capsule and the front face prints "180 CAPSULES", which is the servings figure recorded here.

Price history
Latest recorded price: $41.00 at Thorne (direct), checked . Unchanged since we started checking on Sep 20 (38 checks).
We check each price about once a day, so this is the range we recorded, not necessarily every price there has been. It says what changed, not why, and nothing about where the price goes next.
Verification, Tier A?: Independently certified, package unconfirmed
A certification program lists this product, but its listing does not name the package size priced here, so we do not present it as an unqualified certification. The listing, and exactly what it does and does not cover, is set out below.
- NSF Certified for Sport lists this product, but the listing does not cover the package size shown here. Listed at another size. Listing 1211643 "Thorne® Zinc Picolinate 30 mg" prints Package Size "60" and Serving Size "1 capsule"; this bottle's front face prints "180 CAPSULES". The listing names a 60-capsule package and not this one, whichever 60-capsule SKU it names. Its filed label image prints the serving, the zinc line and the other ingredients this bottle's panel prints (Serving Size: One Capsule; Zinc (as Zinc Picolinate) 30 mg), so it is read as this product at another size. This bottle's own side face prints NSF's Contents Certified mark rather than the Certified for Sport mark, which is recorded as the maker's claim on the product.

What this rests on: prices we last recorded at the retailer named on each product page, which go stale, and each page says when it was checked; the products we track, not every product sold, and Amazon and Walmart are not among the stores; listings and labels read at the source, each linked from the page.
